Measuring device



March 7, 1939. 1. F. sPRuNGER MEASURING DEVICE Filed Dec. 6,A 1957 ATTORNEY` Patented Mar. 7, 1939 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to measuring devices and more particularly to that class used in dispensing liquid from bottles or the like.

One of the principal objects of my invention is to provide means for dispensing a predetermined quantity of liquid from a container.

Another object oi my invention is to provide means for preregulating the quantity of liquid dispensed from a container.

A further object of my invention is to provide means whereby the amount of liquid dispensed from a bottle may be varied at will.

Other objects and advantages will be apparent from the following description, appended claim and annexed drawing.

Referring to the drawing wherein like reierence characters designate like parts throughout the several views:

Fig. i is a side elevation of my invention attached to a bottle.

Fig. 2 is a longitudinal section taken on a line 2-2 of Fig. 3.

Fig. 3 is a sectional View taken on a line 3 3 of Fig. 2,

Fig. i is a cross sectional View taken on a line 4 3 of Fig. 3.

Fig. 5 is a detail sectional View similar to Fig. 2, the parts being shown in a nondispensing position.

The device, a preferred embodiment being illustrated in the drawing described herein, comprises a partitioned housing lil provided with an outlet nozzle and a bottle engaging inlet section i2 adapted to be inserted within the neck of a bottle I3. A suitable liquid passage i4 is formed in the lower part of the housing and laterally thereof and communicates with the outlet nozzle and intake section I2. Positioned above said passage and extending transversely of the housing, there is mounted for rotation therewith a rotor i6 comprising radially extending arms |'l having secured to the outer ends thereof blades i8. Formed above the passage I4 and communieating therewith is an arcuate passage I9 through which the rotor is adapted to rotate. A number of the blades i3 are at all times located within the passage is. Adjacent the passage i4, there is formed a chamber 26 for housing the quantity regulating mechanism.

The mechanism comprises a gear 2| pivotally mounted between rocker arms 22 and 23 pivotally supported within the housing as at 24. A suitable pivot 25 secures the gear 2| to the arms 22 and 23 for rotation thereon relative to said rocker arms. A pendulum 26 is pivotally mounted on the housing by means of a trunnion 21 and adapted to oscillate thereon. The upper end of the pendulum is folded to form a depending section 28 having a slot 23 arranged therein for the Y reception of a pin 36 carried by the upper end of the rocker arm 23. The gear 2| is provided With an outwardly projecting pin 3| adapted to engage a like pin 32 secured to the inner face of the rocker arm 23. Interposed between the rocker arm 23 and gear 2| there is positioned a hair spring 35 having one end connected to the shaft 26 and the opposite end secured to the gear 2 A drive pinion 36 is keyed to the shaft I5 and adapted to drive gear 2| when the device is being operated. A suitable stop comprising a rod 38 having a laterally extending portion 39 is adjustably secured within an arcuate slot 40 formed in the outer wall of the chamber 26. The lateral extending portion 39 of the rod is adapted to engage the pin 3| to prevent rotation of the gear 2| in one direction and the pin 32 coacting with the pin 3| to prevent rotation of the gear in the opposite direction.

An air vent 4| for permitting free flow of liquid is formed in the housing and communicates with an opening 42 in the passage I9 and the inside of the bottle. A tube 42 is connected thereto, within the section |2, and extends within the bottle for preventing liquid entering said vent while the bottle is in the pouring position hereinafter described.

In use, the container or bottle being in the position illustrated in Fig. 5, the pendulum, rocker arms and gear 2| are in lower non-operating position. The gear 2| being disengaged from the pinion 36 and the pin 32 engaging the pin 3| carried by the gear 2|. Tilting the bottle to the position shown in Figures 1 and 2, moves the rocker arms forward through the medium of the pendulum, this movement of the rocker arms causes the gear 2| to engage with the pinion 36; the liquid at the same time flowing through the passage I4 towards the outlet nozzle will revolve the rotor through the medium of the blades and as a result, the pinion 36 mounted on the rotor shaft will cause the gear 2| to rotate until the pin 3| contacts the extended portion 39 of the rod 36. Upon contact with the rod 38 the gear 2| ceases rotation and prevents further rotation of the rotor through the medium of the pinion 36, thereby preventing further ow of liquid to the outlet nozzle It is to be noted, that during the rotation of the gear 2| the hair spring is Wound about the shaft 25 and the resiliency of the spring is such as not to reverse the gear 2l while liquid is dammed against the blades I8. Moving the bottle to a perpendicular position permits the gear and rocker arms to again assume the position illustrated in Fig. 5 through the actuation of the pendulum. In this position, the gear 2l is disengaged from the pinion 36 and rotates in a reverse direction through the medium of the unwinding of the hair spring, thus, bringing the pin 3| into engagement with the pin 32.

The ratio between the pinion and gear determines the quantity of liquid permitted to ow through the passage I4. However, by adjusting the rod 38 in the slot 40, the degree of rotation of the gear 2| is regulated and as a result the amount of liquid being dispensed is also Vregulated in accordance therewith.

It is to be distinctly understood that Various changes and modifications in construction and arrangement of parts may be resorted to without departing from the spirit of the invention or scope of the appended claim,

Having described my invention, what I claim 1s:

A device of the character described, comprising a body having an outlet passage formed therein, a rotor rotatably mounted Within said body and equipped with blades adapted to be operated by a iiow of liquid through said passage; a transversely extending shaft journaled in said housing, connected to said motor and rotatably therewith; a gear mounted on said shaft; a pair of rocker arms pivotally mounted in said housing and having a gear supported therebetween; a pendulum swingable in said housing and connected to said rocker arms and adapted to position said rocker arms in a manner to mesh said second mentioned gear with said first mentioned gear in one position and to position said rocker arms in a manner to disengage said second mentioned gear from said first mentioned gear; an adjustable stop carried by said housing and adapted to engage said second mentioned gear to prevent rotation thereof in one direction when said second mentioned gear is meshed With said first mentioned gear and means connecting said second mentioned gear and said rocker arms for rotating said second mentioned gear when said second mentioned gear is disengaged from said -rst mentioned gear.
